Answer:
Negative numbers don't have real square roots since a square is either positive or 0.
Explanation:
Negative numbers don't have real square roots since a square is either positive or 0.
It depends, but this is how I would do it:
Let's take the square root of -8 --> [tex]\sqrt{-8}[/tex]
First, I would take out an "i" and put it outside of the square root:
[tex]i\sqrt{8}[/tex]
The i represents the negative sign. Then, I would treat the square root of 8 as a normal problem and simplify by factoring it:
Factors of 8: 2,2,2
Because you're looking for a square root and you can "loop" two 2s together, you can take one set out:
[tex]2i\sqrt{2}[/tex] would be your final answer.
Hope I helped :)
